Icon-based home certification, in-home leakage testing, and antenna matching pad

A signal generator for determining leakage at a subscriber's premises in a cable television (CATV) network, the signal generator comprising:

• a frequency source comprising at least one oscillator, the frequency source operable to generate (i) a first test signal having a first frequency in an aeronautical band and a first signal level, and (ii) a second test signal having a second frequency in an Long Term Evolution (LTE) band and a second signal level, wherein the first and second signal levels are each 40 dB to 70 dB above a third signal level of a cable signal supplied by the CATV network;
• shielding at the signal generator to prevent radiation over the air of the first and second test signals from the signal generator;
• and
• a connector configured to be secured to a network port at the subscriber's premises to electrically couple the frequency source to cable wiring at the subscriber's premises, in order to supply the first and second test signals through the connector and the network port to the cable wiring at the subscriber's premises, wherein the connector is configured to be secured to the network port in order to supply the first and second test signals through the connector and the network port to the cable wiring at the subscriber's premises for maintaining a high power offset between the first and second test signals and the cable signal supplied by the CATV network, wherein the third signal level of the cable signal supplied by the CATV network is in a range of −5 dBmV to 0 dBmV.
